The morning after pill is a type of emergency contraception designed to prevent pregnancies after unprotected sex, either because your regular contraception failed (a split condom, for example) or you didn’t use anything.

There are two main brands of morning after pill in the UK – ellaOne and Levonelle. They work in a similar way, but may be taken differently. To be effective, ellaOne must be taken within 120 hours (five days) of unprotected sex and Levonelle within 72 hours (three days).
